An anonymous reader writes: One of the biggest changes Microsoft announced for Windows 8 was the change from the "Aero Glass" interface we had in Windows Vista and Windows 7 to a new Metro UI. Until today these changes had not been fully seen as the weren't included in the recent Release Preview.
A number of changes have been made to the UI since the Release Preview 2 weeks ago. Microsoft have said the new Metro UI will appear crisper following the removal of shadows and transparency. Gradients have been removed from buttons. The task bar is no longer has the glass, transparent look or blur effect.
The new design brings with it some heartache for those that loved the Aero Glass effect as it has now been completely removed from Windows 8.Link to Original Source
